Step-by-step explanation:
1. Find the GCF (Greatest Common Factor)
2. Factor out the GCF and simplify.
3. Factor 
Which two numbers add up to -1 and multiply to -6?
<u>-3 and 2</u>
Rewrite the expression using the numbers above.
4. Done!
48.59° is your answer.
Soh Cah Toa
Looking at the unknown angle, you know the opposite angle(45) and the hypotenuse(60). Opposite and hypotenuse is Soh which is sin.
Sinx = 45/60(opposite/hypotenuse)
(sin-1*)sinx = 45/60 (*sin-1) ----multliply by sin-1 (inverse)
The sins cancel leaving you with...
x = sin-1(45/60)
If you plug that into a calculator you should get about 48.59°.
Answer: I got the answer of -7/2
Step-by-step explanation:
8
x
+3=
1
x
+1
Multiply all terms by x and cancel:
8+3x=1+1x
3x+8=x+1(Simplify both sides of the equation)
3x+8−x=x+1−x(Subtract x from both sides)
2x+8=1
2x+8−8=1−8(Subtract 8 from both sides)
2x=−7
2x
2
=
−7
2
(Divide both sides by 2)
x=
−7
2
Check answers. (Plug them in to make sure they work.)
x=
−7
/2
(Works in original equation)
